T-Mobile to advertise to unlocked iPhone customers, sway them away from AT&T promising $1500 savings over 2 years

A report surfaced this morning about T-Mobile sending a memo to its sales staff that encourages them to sell against Apple’s iPhone beginning Sept. 21. Unsurprisingly, the memo confirmed T-Mobile would not be a carrier for the next-generation iPhone due out next month. Adding a bit to this morning’s story, TmoNews followed up with a new flyer that T-Mobile aims to show customers. The flyer boasts just how much iPhone users will save if they ditch AT&T and bring their unlocked iPhone to T-Mobile. Magenta is promising customers can save up to $1,500 over two years if they switch. T-Mobile’s single line offering actually sounds fabulous, as it offers customers truly unlimited data, text and minutes for only $75. That seems like a plan you can’t beat…unless you want 3G speeds. T-Mobile made a recent push to iPhone-compatible 1900MHz 3G network (and 4G at WWDC), but we are not sure how well it is doing on that front. Until then, EDGE 2.5G is as fast as you will get.

T-Mobile has not been able to sign up as an official iPhone carrier, so it has always made strides to welcome unlocked iPhone users. We previously reported there are roughly 1 million iPhone users on T-Mobile’s network. T-Mobile offers a MicroSIM kit to make the switch on your iPhone 4 or iPhone 4S a little easier. An updated version of the kit will hit stores beginning Aug. 29.

Considering the amount of savings that can be had, it may not be a bad idea to switch over to T-Mobile if you are in a low-speed area. We are not exactly sure why T-Mobile singled out just AT&T, but we suspect the savings are close to the same across Verizon and Sprint. Making the switch to T-Mobile all depends on what kind of coverage you get in your area and if you feel comfortable ditching 4G LTE when the new iPhone lands.
